The ancient genetic record reveals the negative changes in oral bacteria brought about by the dietary shifts as humans became farmers, and later with the in- troduction of food manufacturing in the Industrial Revolution. An international team, led by the Uni- versity of Adelaide's Centre for Ancient DNA (ACAD) in Australia, where the re- search was performed, published the results in Nature Genetics in February. Other team members include the Depart- ment of Archaeology at the University of Aberdeen and the Wellcome Trust Sanger Institute in Cambridge, United Kingdom. “This is the first record of how our evolution over the last 7,500 years has impacted the bacteria we carry with us, and the important health consequences,” said study leader professor Alan Cooper, ACAD director. “Oral bacteria in modern man are markedly less diverse than his- toric populations, and this is thought to contribute to chronic oral and other dis- ease in post-industrial lifestyles.” The researchers extracted DNA from tartar (calcified dental plaque) from 34 prehistoric northern European human skeletons and traced changes in the na- ture of oral bacteria from the last hunter- gatherers, through the first farmers to the Bronze Age and Medieval times. Dental plaque represents the only eas- ily accessible source of preserved human bacteria,” said lead author Dr. Christina Adler, who conducted the research as a PhD student at the University of Adelaide and is now at the University of Sydney. “Genetic analysis of plaque can create a powerful new record of dietary impacts, health changes and oral pathogen ge- nomic evolution, deep into the past,” she said. Cooper said, “The composition of oral bacteria changed markedly with the in- troduction of farming, and again around 150 years ago. With the introduction of processed sugar and flour in the Industri- al Revolution, we can see a dramatically decreased diversity in our oral bacteria, allowing domination by caries-causing strains. The modern mouth basically ex- ists in a permanent disease state.” Cooper has been working on the project for the past 17 years with archaeologist and co-leader Keith Dobney, a professor at the University of Aberdeen. Dobney said, "I had shown tartar deposits com- monly found on ancient teeth were dense masses of solid calcified bacteria and Ancient teeth bacteria track disease evolution ” See pages A4–A5 The Thomas P.
